The NBA postponed Monday's game due to slippery conditions on the court at Target Center caused by condensation.

A sub-court sheet of ice and unseasonably humid weather in Minneapolis combined to bump Monday's scheduled game between the Portland Trail Blazers and Minnesota Timberwolves to a later date.

The NBA postponed the game due to slippery conditions on the court at Target Center caused by condensation, which formed from an ice sheet beneath the surface and temperatures during the day.

A makeup date will be announced later this week.

It is the second time this season an NBA game had to be put on hold due to ice-induced condensation. But unlike the Sacramento Kings and Philadelphia 76ers at Wells Fargo Center, the Timberwolves do not share Target Center with an NHL franchise.

The culprit this time was a "Disney on Ice" production that hit the Twin Cities over the weekend.

The travelling spectacle held nine performances of its "Dream Big" show between Wednesday and Sunday, and the ice was left in place for the upcoming National Collegiate Hockey Conference tournament held inside the arena.

Players from both teams voiced their concerns over the dangerous playing surface upon taking the court for their warmup routines.

"It was [wet] everywhere," Timberwolves guard Kris Dunn told reporters before the game was postponed. "That's like playing tennis in the rain. It's just not happening. It just won't happen."

An arena maintenance crew attempted to mop up the condensation in time for the 20:00 (local time) tip-off to no avail.

"I'd like to apologise to our fans and certainly to the Trail Blazers," Timberwolves president and coach Tom Thibodeau said. "Obviously the safety of the players has to come first. It's unfortunate, but it's the right thing to do."
